SPECIFICATION forming part of Letters Patent No. 247,406, datedSeptember 20, 1881.

' Application filed July 15, 1881. (ModeL) To all whom it may concern:

Be it known that I, NATHAN PURDY, of Fall Brook, in the county of Tiogaand State of Pennsylvania, have invented a new and Improved Pipe-Tongs,of which the following is a specification.

My invention consists in linking thejaws of the tongs together at theirouter ends and linking one of the jaws permanently to the end of thehandle or lever, the other jaw being adapted to be connected to thelever so as to grasp upon the pipe by means of a loop or similar devicehinged or pivoted upon the end of the lever, and adapted to be placedover the end of said jaw, as hereinafter more fully described.

In the accompanying drawings Figure 1 is a side view of my improvedtongs. Fig. 2 is a view of the edge or back of the tongs, and Fig. 3 isa cross-section on the line 00 w of Fig. 1.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the handle or lever; and B B represent thejaws, which are serrated upon their inner faces as shown. The

jaw B is attached permanently to the end of the lever by means of eye a,formed on the end of the lever and the hook 1) formed on the end of thejaw, and one end of the jaw B is permanently attached to the outer endof the jaw B by means of the strong link d, which is of sufficientlength to permit the jaw B to be placed over and upon the pipe to beturned. The other end of this jaw is formed into the hook h, so thatwhen the jawis placed over and 3 5 upon the pipe the swinging loop orlink D, which is bolted to the lever by the holtj, may

be placed over the hook h, as shown in Fig. 1, and thus secure the tongsupon the pipe. When the tongs are thus attached to the pipe, upon powerbeing applied to the lever the jaws will automatically grasp upon thepipe by the action of the links, and thus relieve the operator of thenecessity of griping the tongs upon the pipe by hand-power, as with thetongs of 5 ordinary construction; and when the lever is brought toposition for taking a new hold upon the pipe the jaws of their ownweight will turn upon the pipe to the proper position, ready to againgrasp the pipe firmly when poweris again applied to the lever.

These tongs are strong, durable, cheap of construction, and, as appearsfrom the above description, easily and quickly operated, and they arenot liable to get out of order.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- The combination,with the lever A, provided with the eye a and pivoted link D at itslower end, of the jaws B B, having at their upper ends the hooks b andh, and connected together at their lower ends by link d, substantiallyasherein shown and described.

NATHAN PURDY.
